This installation method can damage the net and is inconvenient to assemble. Furthermore, screw fixation poses a risk of rust after prolonged use, and rust debris can enter the room with the airflow, affecting air quality. Utility Model Content

[0004] The present application aims to solve the above technical problem, namely, to solve the problem that the air outlet guard net in the mobile air conditioner is easily damaged and inconvenient to assemble, so as to avoid affecting the air outlet quality.

[0005] The present application provides a mobile air conditioner, comprising: an outer shell, which defines an indoor heat exchange chamber internally, and an indoor air outlet arranged corresponding to the indoor heat exchange chamber on the outer shell; an indoor fan assembly, which is arranged in the indoor heat exchange chamber, and comprises a fan volute, and the top of the fan volute is provided with an indoor fan outlet arranged corresponding to the indoor air outlet; a positioning member and a fixing member relatively arranged in the fan volute and located at two side ends of the indoor fan outlet, the positioning member having a positioning hook extending in a direction away from the fixing member, and the fixing member having a fixing hole groove extending along a first direction; an air outlet protective net comprising at least a first mesh extending in the first direction and a second mesh and a third mesh respectively located at both ends of the first mesh; the first mesh can be clamped in the fixing hole groove, and the second mesh can abut against the side of the fixing hole groove away from the positioning member, and the third mesh can be clamped on the positioning hook.

[0006] When adopting the above technical solution, the air outlet screen primarily serves as a protective barrier, preventing children or other personnel from reaching into the interior of the indoor fan assembly when the indoor air outlet is open, thereby ensuring the safety and reliability of the indoor fan assembly. Furthermore, by providing the fixing slots that cooperate with the first and second mesh threads of the air outlet screen, and by cooperating with the positioning hooks and the third mesh thread, the air outlet screen can be installed stably and quickly, preventing damage to the air outlet screen. Furthermore, the air outlet screen can be made removable for easy disassembly and cleaning.

[0007] In an optional embodiment of the above-mentioned mobile air conditioner, the positioning member includes: a positioning base, fixed to the fan volute, including a first side facing away from the fixing member; a positioning plate, arranged on the first side and extending in a direction away from the fixing member, and a positioning hook is defined between the positioning plate and the fan volute, and the third mesh can be hooked on the positioning hook.

[0008] In this way, the positioning hook formed by the cooperation of the positioning base and the positioning plate can cooperate with the third mesh of the air outlet guard net, so that the third mesh wire is hooked on the positioning hook to achieve the positioning of this side end of the air outlet guard net, which is convenient for installation.

[0009] In an optional implementation scheme of the above mobile air conditioner, the third mesh is provided with a connecting hook bent toward the fan volute, and the connecting hook cooperates with the positioning hook.

[0010] By cooperating with the connecting hook and the positioning hook, the positioning piece and the air outlet guard net can be closely matched, thereby improving the stability of the installation of the air outlet guard net.

[0012] The provision of the guide member can improve the installation of the second side end of the air outlet guard net. During installation, the second side end can be placed on the first guide side and slide downward, which is convenient for positioning and installation and improves installation efficiency.

[0013] In an optional embodiment of the mobile air conditioner, a plurality of positioning members are arranged at intervals along the extension direction of the third mesh; and corresponding to each positioning member, at least two guide members are arranged at intervals.

[0014] By providing multiple positioning members, the stability of the side end provided with the air outlet guard and the third mesh can be improved after installation. At the same time, at least two guide members are arranged at intervals corresponding to each positioning member, which can further improve the stability of the third mesh or the connecting hook during installation and improve installation efficiency.

[0016] By setting the raised parts and making the distance between the two raised parts smaller than the diameter of the first mesh, force is applied during installation to make the first mesh pass through and be installed in the fixed hole groove, which can prevent the first mesh from falling out of the fixed hole groove and improve the safety of the air outlet guard net after installation.

[0017] In an optional embodiment of the above mobile air conditioner, both of the two protrusions have a second guide side surface, and the distance between the two second guide side surfaces gradually decreases from top to bottom.

[0018] By providing the second guide side surface, the first mesh can be guided when it moves toward the bottom of the fixing hole, thereby improving installation efficiency.

[0019] In an optional implementation scheme of the above mobile air conditioner, the air outlet guard net further includes: a plurality of fourth meshes, which are spaced between the second mesh and the third mesh and cross-connected with the first mesh.

[0020] By disposing the fourth mesh, the structural stability of the first mesh between the second mesh and the third mesh can be improved, and connection support can be provided for the plurality of first meshes.

[0021] In an optional embodiment of the mobile air conditioner, a distance between two adjacent fourth meshes is greater than a distance between two adjacent first meshes.

[0022] By setting the distance between two adjacent fourth meshes to be greater than the distance between two adjacent first meshes, not only the structural strength of the air outlet guard net can be improved, but also the structure of the air outlet guard net can be simplified, the number of fourth meshes can be reduced, and the cost can be reduced.

[0023] In an optional embodiment of the above mobile air conditioner, the surface of the air outlet guard is coated with a bactericidal coating.

[0024] By setting up the bactericidal coating, the airflow passing through the air outlet guard net can be sterilized and purified to a certain extent, thereby improving the cleanliness of the air outlet airflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] Combine Figures 1 to 9 As shown, the present application provides a mobile air conditioner, including a housing 100, an indoor fan assembly 200, a positioning member 300, a fixing member 400 and an air outlet guard net 500.

[0049] The interior of the housing 100 defines an indoor heat exchange chamber 110, and the housing 100 is provided with an indoor air outlet 111 arranged corresponding to the indoor heat exchange chamber 110. The indoor fan assembly 200 is disposed within the indoor heat exchange chamber 110. The indoor fan assembly 200 includes a fan volute, the top of which is provided with an indoor fan outlet 201 arranged corresponding to the indoor air outlet 111. Positioning members 300 and fixing members 400 are respectively provided on the fan volute and at the two side ends of the indoor fan outlet 201. The positioning member 300 has a positioning hook 301 extending in a direction away from the fixing member 400, and the fixing member 400 has a fixing slot 401 extending along a first direction.

[0050] The air outlet screen 500 is positioned at the indoor fan outlet 201 and covers at least the indoor fan outlet 201. The air outlet screen 500 comprises at least a first mesh 510 extending in a first direction, and second and third meshes 520 and 530 located at opposite ends of the first mesh 510 and intersecting the first mesh 510. The first mesh 510 can be secured to the fixing slot 401, the second mesh 520 can abut the side of the fixing slot 401 facing away from the positioning member 300, and the third mesh 530 can be secured to the positioning hook 301.

[0051] Optionally, the interior of the shell 100 is a cavity structure, and a middle partition is provided in the cavity. The middle partition can separate the cavity into an indoor heat exchange cavity 110 and an outdoor heat exchange cavity 120 distributed up and down. Among them, an indoor heat exchanger 600 and an indoor fan assembly 200 are provided on the middle partition. Correspondingly, an indoor air inlet 112 and an indoor air outlet 111 are provided on the shell 100 corresponding to the indoor heat exchange cavity 110, so that the indoor air can circulate in the indoor heat exchange cavity 110, and after exchanging heat with the indoor heat exchanger 600, it flows back to the room through the indoor air outlet 111 to achieve the regulation of the indoor temperature. Specifically, the indoor air inlet 112 is provided on the back plate 102 of the shell 100, and the indoor air outlet 111 is provided on the top plate 101 of the shell to improve the aesthetics of the shell 100.

[0052] Furthermore, an outdoor heat exchange assembly is provided below the partition, i.e., in the outdoor heat exchange chamber. The outdoor heat exchange assembly includes an outdoor fan assembly and an outdoor heat exchanger. Furthermore, a compressor is also provided in the outdoor heat exchange chamber. An outdoor air inlet and an outdoor air outlet are provided on the housing 100 corresponding to the outdoor heat exchange chamber. The compressor, the outdoor heat exchanger, and the outdoor fan assembly are sequentially provided between the outdoor air inlet and the outdoor air outlet along the flow direction of the airflow. When the indoor fan assembly 200 is in operation, it drives the air to flow through the outdoor air inlet and then through the compressor and the outdoor heat exchanger in sequence to cool the two. Furthermore, the air after heat exchange, driven by the outdoor fan assembly, flows out of the outdoor heat exchange chamber through the outdoor air outlet.

[0053] Optionally, the top of the fan volute of the indoor fan assembly 200 is formed with an indoor fan outlet 201 facing the indoor air outlet 111, thereby reducing airflow loss. To prevent a user from inserting their hand into the indoor fan assembly 200 when the indoor air outlet 111 is open, an air outlet screen 500 is provided at the indoor fan outlet 201 for protection. Furthermore, the fan volute is provided with a positioning member 300 and a fixing member 400 at each side of the indoor fan outlet 201, respectively, for detachably attaching and mounting the air outlet screen 500.

[0054] The air outlet screen 500 is capable of covering at least the indoor fan outlet 201 and extends along the length of the indoor fan outlet 201. The positioning member 300 and the fixing member 400 are respectively disposed at two side ends in the length direction of the indoor fan outlet 201. The positioning member 300 has a positioning hook 301 extending in a direction away from the fixing member 400, and the fixing member 400 has a fixing slot 401 extending along a first direction.

[0055] Furthermore, the air outlet screen 500 includes at least a first mesh 510, a second mesh 520, and a third mesh 530. The first mesh 510 extends in a first direction, and the second mesh 520 and third mesh 530 are respectively connected to the ends of the first mesh 510, that is, located at the two side ends of the air outlet screen 500. The first mesh 510 can be fixed to the fixing slot 401, and the second mesh 520 can abut the side of the fixing slot 401 facing away from the positioning member 300. The third mesh 530 can be fixed to the positioning hook 301. In this way, the coordination between the fixing slot 401 and the first and second mesh 510, 520, and the coordination between the positioning hook 301 and the third mesh 530 can achieve stable installation of the air outlet screen 500. At the same time, the air outlet screen 500 is removable for easy disassembly and cleaning.

[0056] The first direction is the length direction of the indoor fan outlet 201. The extension directions of the second mesh 520 and the third mesh 530 can be the same or different.

[0057] Preferably, the second mesh 520 and the third mesh 530 are perpendicular to the first direction, that is, the width direction of the indoor fan outlet 201. In this way, the structural strength of the air outlet protective net 500 can be improved.

[0058] Optionally, the housing 100 includes a left side panel and a right side panel that are arranged opposite to each other, and a front side panel and a back side panel that are arranged opposite to each other. The indoor fan assembly 200 can be arranged to extend from the left side panel to the right side panel, in which case the length direction of the indoor fan outlet 201, i.e., the first direction, is from the left side panel to the right side panel. Alternatively, the indoor fan assembly 200 can be arranged to extend from the front side panel to the back panel, in which case the length direction of the indoor fan outlet 201, i.e., the first direction, is from the front side panel to the back panel.

[0059] When the above-mentioned technical solution is adopted, the provision of the air outlet guard net 500 mainly plays a protective role, preventing children or other personnel from putting their hands into the interior of the indoor fan assembly 200 when the indoor air outlet 111 is open, thereby ensuring the safety and reliability of the indoor fan assembly 200; further, by providing the fixing hole groove 401 and cooperating with the first mesh 510 and the second mesh 520 of the air outlet guard net 500, and by cooperating with the positioning hook 301 and the third mesh 530, the air outlet guard net 500 can be stably installed to avoid damage to the air outlet guard net 500; at the same time, the air outlet guard net 500 can be made detachable for easy disassembly and cleaning.

[0060] In the aforementioned alternative embodiment of the mobile air conditioner, the positioning member 300 includes a positioning base 310 and a positioning plate 320. The positioning base 310 is fixed to the fan volute and includes a first side surface facing away from the fixing member 400. The positioning plate 320 is disposed on the first side surface and extends away from the fixing member 400. A positioning hook 301 is defined between the positioning plate 320 and the fan volute, and the third mesh 530 can be hooked to the positioning hook 301.

[0061] In this way, the positioning hook 301 formed by the cooperation of the positioning base 310 and the positioning plate 320 can cooperate with the third mesh 530 of the air outlet guard net 500, so that the third mesh 530 is hooked on the positioning hook 301 to achieve the positioning of this side end of the air outlet guard net 500, which is convenient for installation.

[0062] Optionally, a connecting piece is provided on the third mesh 530 , and the connecting piece can be hooked on the positioning hook 301 to achieve the connection between the air outlet guard net 500 and the positioning piece 300 , thereby achieving the positioning of the air outlet guard net 500 .

The second mesh 520 and the third mesh 530 are both fixedly connected to the first mesh 510. The second side end faces the positioning member 300.

[0064] In the optional embodiment of the mobile air conditioner, a connecting hook 550 bent toward the fan volute is provided on the third mesh 530 , and the connecting hook 550 cooperates with the positioning hook 301 .

[0065] By cooperating with the connecting hook 550 and the positioning hook 301 , the positioning member 300 and the air outlet guard net 500 can be closely matched, thereby improving the installation stability of the air outlet guard net 500 .

[0066] Optionally, two adjacent or spaced first mesh wires 510 are connected together at one end (i.e., the end located at the second side end) of the positioning member 300 to form a connecting hook 550. Specifically, the ends of the two adjacent or spaced first mesh wires 510 located at the second side end have a bent section that bends and extends toward the fan volute, and the two bent sections are connected to each other. In this way, the connecting hook 550 can be formed.

[0067] Alternatively, the connection hook 550 may not be provided.

[0068] In an optional embodiment of the mobile air conditioner, a guide member 700 is further included. The guide member 700 is spaced apart from the positioning member 300 and is disposed on the fan volute. The guide member 700 includes a first guide side surface 710 facing the positioning hook 301. The first guide side surface 710 extends obliquely from the top to the bottom toward the positioning hook 301. The first guide side surface 710 is configured to guide the movement of the third mesh 530 or the connecting hook 550 toward the positioning hook 301.

[0069] The installation of the second side end of the wind screen 500 can be improved by setting the guide member 700. During installation, the second side end can be placed on the first guide side 710 and slide downward, which is convenient for positioning and installation and improves installation efficiency.

[0070] In addition, the guide member 700 and the positioning member 300 are spaced apart to form a gap, so that a limit stop can be formed on the second side end of the air outlet guard net 500 after installation to prevent the second side end from falling out.

[0071] Alternatively, the guide member 700 may not be provided.

[0072] In an optional embodiment of the mobile air conditioner, a plurality of positioning members 300 are arranged at intervals along the extension direction of the third mesh 530 ; and corresponding to each positioning member 300 , at least two guide members 700 are arranged at intervals.

[0073] By providing multiple positioning members 300, the stability of the side (i.e., the second side) of the air outlet guard 500 with the third mesh 530 can be improved after installation. Furthermore, at least two guide members 700 are arranged spaced apart for each positioning member 300, further improving the stability of the third mesh 530 or the connecting hook 550 during installation and enhancing installation efficiency.

[0074] Optionally, the connecting hooks 550 and the positioning members 300 are arranged in a one-to-one correspondence.

[0075] Alternatively, only one positioning member 300 is provided.

[0076] Alternatively, only one guide member 700 is provided corresponding to the positioning member 300 .

[0077] In the aforementioned alternative embodiment of the mobile air conditioner, the fixing slot 401 includes a first side rib 410 and a second side rib 420 arranged opposite each other, with a gap between the first and second side ribs sufficient to accommodate the first mesh. The mobile air conditioner also includes two raised portions 430, disposed on the facing sides of the first and second side ribs 410, 420, respectively. The distance between the two raised portions 430 is less than the diameter of the first mesh 510.

[0078] By setting the protrusion 430 and making the distance between the two protrusions 430 smaller than the diameter of the first mesh 510, force is applied during installation to make the first mesh 510 pass through and be installed in the fixing hole groove 401, which can prevent the first mesh 510 from falling out of the fixing hole groove 401, thereby improving the safety of the air outlet guard net 500 after installation.

[0079] Optionally, the fixing hole slot 401 includes at least a first side rib 410 and a second side rib 420 arranged opposite each other, and the first side rib 410 and the second side rib 420 both extend vertically, or extend obliquely from bottom to top in a direction away from the fan volute. Any first mesh 510 is stuck in the fixing hole slot 401, and the second mesh 520 located at the first side end abuts against the side of the first side rib 410 and the second side rib 420 facing away from the positioning member 300 to achieve the installation and fixation of the first side end of the air outlet guard net 500. Furthermore, by providing two protrusions 430 and making the distance between the two protrusions 430 less than the diameter of the first mesh 510, the first mesh 510 can be prevented from falling out of the fixing hole slot 401.

[0080] Optionally, the protrusion 430 is a rectangular protrusion. Alternatively, the protrusion 430 is a hemispherical protrusion.

[0081] Alternatively, one of the first side rib 410 and the second side rib 420 is provided with a protrusion 430. Alternatively, neither the first side rib 410 nor the second side rib 420 is provided with a protrusion.

[0082] Optionally, one or more fixing members 400 are arranged at intervals along the extending direction of the second mesh 520 .

[0083] In an optional embodiment of the mobile air conditioner, the two protrusions 430 each have a second guide side surface 431 , and the distance between the two second guide side surfaces 431 gradually decreases from top to bottom.

[0084] By providing the second guide side surface 431 , the first mesh wire 510 can be guided when moving toward the bottom wall of the fixing hole 401 , thereby improving installation efficiency.

[0085] Alternatively, one of the two protrusions 430 is provided with the second guide side surface 431. Alternatively, neither of the two protrusions 430 is provided with the second guide side surface 431.

[0086] When installing the wind outlet protective net 500 , the second side end of the wind outlet protective net 500 may be positioned and fixed first, and then the first side end of the wind outlet protective net 500 may be fixed and installed.

[0087] In an optional embodiment of the mobile air conditioner, the air outlet guard 500 further includes a plurality of fourth meshes 540 , which are spaced apart between the second meshes 520 and the third meshes 530 and cross-connected with the first meshes 510 .

[0088] By disposing the fourth mesh 540 , the structural stability of the first mesh 510 between the second mesh 520 and the third mesh 530 can be improved, and connection support can be provided for the plurality of first meshes 510 .

[0089] Optionally, the fourth mesh 540 extends in the same direction as the second mesh 520 and / or the third mesh 530. Preferably, the fourth mesh 540 is perpendicular to the first mesh 510.

[0090] Optionally, a gap is formed between the third mesh 530 and the adjacent fourth mesh 540, and the gap allows the positioning base 310 and the positioning plate 320 to pass through, so that the third mesh 530 can be hooked in the positioning hook 301 to achieve the positioning and installation of the second side end of the wind outlet guard net 500.

[0091] Alternatively, the extending direction of the fourth mesh 540 may cross the extending direction of the second mesh 520 and / or the third mesh 530 .

[0092] Alternatively, the fourth mesh 540 is not provided.

[0093] In an optional embodiment of the mobile air conditioner, the distance between two adjacent fourth meshes 540 is greater than the distance between two adjacent first meshes 510 .

[0094] By setting the distance between two adjacent fourth meshes 540 to be greater than the distance between two adjacent first meshes 510, not only the structural strength of the wind outlet guard net 500 can be improved, but also the structure of the wind outlet guard net 500 can be simplified, the number of fourth meshes 540 can be reduced, and the cost can be reduced.

[0095] In an optional embodiment of the above mobile air conditioner, the surface of the air outlet guard 500 is coated with a bactericidal coating.

[0096] By setting the bactericidal coating, the airflow passing through the air outlet guard net 500 can be sterilized and purified to a certain extent, thereby improving the cleanliness of the air outlet airflow.

[0097] Specifically, the surface of the air outlet guard 500 is coated with a silver ion air purification film layer. This allows the air outlet guard 500 to have a sterilization and purification function on the air flowing through it, so that the airflow passing through the air outlet guard 500 is sterilized and purified to a certain extent, improving the cleanliness of the airflow and the comfort of the user.

[0098] Alternatively, the air outlet guard net 500 itself can also have a sterilization and purification function, that is, when the air outlet guard net 500 is produced, a purification material containing silver ions is mixed into the production material of the air outlet guard net 500. In this way, the formed air outlet guard net 500 itself can have a sterilization and purification function, thereby realizing the sterilization and purification of the air flow passing through the air outlet guard net 500.

At the same time, such a configuration can enable the second volute 220 to be connected to the first volute 210 in a slot-type manner. During installation, the cooperation between the installation notch 213 and the first extension 2211, and the cooperation between the avoidance notch 215 and the second extension 2221, can ensure the accurate positioning of the second volute 220 and improve installation efficiency.

[0107] Optionally, the first volute tongue 214 and the second volute tongue 222 are both configured to be arc-shaped to prevent airflow from circulating in the indoor fan assembly 200 .

[0108] Furthermore, the positioning member 300 is provided on the second volute tongue 222 and / or the second extension portion 2221 . The fixing member 400 is provided on the mounting platform 221 and the first extension portion 2211 .
